Walking inside, there is the dock room.

"What are those piers for?" Xiao Zan asked, pointing to the floor of the dock room.

Chen Zheng glanced at it and replied, "These are keel piers and side piers set on the bottom plate, which are used to support the ship. ”

Without waiting for others to continue to ask, Chen Zheng continued to introduce: "The dock head in front is opposite to the dock mouth, and I designed a semicircle, which looks relatively open. ”

"What is this for?" Xiao Zan looked like he didn't understand and asked.

"The space here is actually part of the dock." Chen Zhengdao, "Here, we can disassemble and assemble, and in addition, painting the surface of the ship is also carried out here." ”

Xiao Zan listened very carefully, but unfortunately, he didn't understand.

Because there are no ships made now, and there are no ships to rest here, it is difficult for Xiao Zan to imagine based on Chen Zheng's description alone.

Chen Zheng also saw Xiao Zan's confusion, just talking like this, it was really difficult to understand, but his task was to introduce it to the craftsmen.

Whether you understand it or not, that's your business.

Li Shuang looked at it, if he explained it like this, it would have no effect at all, and the key Shui Xiaozan seemed to be getting more and more confused.

However, it seemed that their luck was better, and at this moment, there was a shout from outside, which turned out to be a sea ship, which was going to be repaired in the dock.

When Chen Zheng saw it, he quickly led everyone out of the dock room and came to the second floor of the dock.

At this time, some workers in the dock opened the irrigation facilities at the dock pier and began to fill the dock with water, and it didn't take long for the water level inside the dock to be level with the outside of the dock.

At this time, the dock door was opened again, and a sea ship slowly sailed into the dock.

Liu Bin looked very carefully and asked, "Master Chen, there is no oars on the boat, how did you get in?" ”

Li Shuang knew this answer, wanted to show off, took a step forward, and said, "That's a good question, have you seen the ropes that tug the sea boat?" ”

Liu Bin nodded and said, "I saw it, but I didn't see anyone pulling." ”

Li Shuang smiled slightly and said, "Look at the end of the rope, there is only a small opening there, and there is a hole in it." ”

"What's in there?" Liu Bin was dying, "You said it." ”

"Tut-tut, what are you anxious about? I'm not talking about it. Li Shuang was a little impatient, "There is a wooden winch in there, you only need to turn the winch to pull the rope forward, and the sea ship will naturally be pulled in." ”

"How many people do you need? This sea ship is not small. Liu Bin said, while estimating the number of people inside.

Li Shuang put his hands behind his back and said, "As you can see, one rope on one side, that is, one person on one side." ”

"Impossible!" Liu Bin said categorically, "How can two people pull such a big sea boat." ”

Li Shuang became even more impatient, and said: "That winch rotates very lightly, just take these people here as an example, except for Yang Xiaoping, who is useless to read with, everyone else can turn!" ”

Yang Xiaoping: "......"

didn't recruit anyone to provoke anyone, lying down for no reason, Yang Xiaoping felt a little aggrieved, but seeing that the prince Xiao Zan listened to it with relish, he also knew that this was not the time to interject.

However, Yang Xiaoping silently kept this account in his heart, and when the time was ripe, it would not be too late to take revenge.

But Liu Bin still didn't believe it, shook his head and said: "How can there be such a winch, this is a big sea ship!" ”

Li Shuang only knew what it was, but he didn't know why, so he had to say: "This winch is made by Brother Chen, it is naturally brisk, you don't believe it." ”

Liu Bin frowned and asked, "You said that the winch was made by Master Chen?" ”

"That's right!" Li Shuang nodded, "If you don't believe it, try it yourself." ”

"My heart!" Liu Bin said directly, "Master Chen's skills are ingenious and superb, even if he tells me that the winch automatically pulls the ship forward, I believe it!" ”

Li Shuang was very unhappy when he heard this, and said: "Master Liu, I didn't expect you to look honest and loyal, but in fact, this double standard is really handy, why do you believe that this thing is made by Brother Chen, and you don't believe it when others do it?" ”

Liu Bin was also sincere, nodded directly, and said: "So far, Master Chen is the craftsman I admire the most, and I can't believe the skills of others!" ”

"You!" Li Shuang was a little speechless, "I can really lift the bar." ”

Chen Zheng didn't expect that this Liu Bin would become his little fan brother, oh no, it should be a little fan brother, he looks much better than himself.

Since people worship him so much, Chen Zheng felt the need to tell him the principle of the winch.

Chen Zheng walked up to Liu Bin and said to him, "Actually, the principle of that winch is very simple, I can tell you." ”

Liu Bin was overjoyed and said, "I wish to listen to you." ”

The other craftsmen, including Xiao Zan, pricked up their ears to hear the principle of the winch that Chen Zheng had said.

As soon as Chen Zheng saw that so many people were interested, he told them the principles of his design.

The principle of winch labor-saving is very simple, but it is a gearbox principle, the big gear drives the small pinion, and the torque transmission changes the size of the force.

According to the law of conservation of energy, if you want to move the sea ship to the dock, the work done is certain and cannot be reduced.

Chen got this inspiration from the shifting bikes of his time, and if he wanted to win, he had to put the chain on the big gear wheel, but that way, he could pedal the bike around less distance.

And although it takes much more effort to pull the chain to the small plate, it may be several times the distance of the chain on the large plate when you pedal the bicycle in one lap.

How to choose, it depends on the needs of the cyclist.

As soon as this simple truth is explained, many experienced craftsmen will understand, but Xiao Zan, who has no life experience, has not understood.

Chen Zheng was a little helpless, so he said to Xiao Zan: "Brother Xiao, otherwise, you will try it yourself?" ”

Yang Xiaoping felt that this was an opportunity, so he jumped out and shouted: "Chen Zheng, you are presumptuous, you actually let our son-in-law work for you, what a crime!" ”

It's just that as soon as Yang Xiaoping finished speaking, he was kicked aside by Xiao Zan and said, "Something like a dog, get out of the way, don't disturb my son's study!" ”

Li Shuang looked at it and hurriedly said: "Brother Xiao's thirst for knowledge is really moved, so let's take this sea ship in by ourselves, how about it?" ”

Xiao Zan was very amused and said, "This is wonderful, Brother Li, please!" ”

"Brother Xiao, please!"
